I am working on a WPF app that is built upon the Prism framework. I am trying to use a binding redirect so that I can substitute an assembly that I have built locally for one that was built on the build system.
It appears from the fusion log that sometimes the redirect is used and sometimes it is not. This is all from the same log from the same attempt to run the application:
Successful load in fusion log:
*** Assembly Binder Log Entry (8/20/2015 @ 11:54:39 AM) ***
The operation was successful.
Bind result: hr = 0x0. The operation completed successfully.

Now the failure to load:

The operation failed.

Two interesting things that I noticed in the failure:
- The failed load has "Calling assembly : (Unknown)"
- Although the correct app config file is referenced, there is no message about a redirect being found
Here is a stack trace that shows how load is being called:
